All floors are not created equal, or evenly-sized. Rugs, however, often come in a pretty standard set of dimensions that may or may not suit the space you've got available in your living room. The Perfect Rug, a San Francisco-based company, aims to get the fit just right. You can choose from a vast collction of styles and materials, customize your shape—it doesn't have to be a standard square, rectangle, or circle—and border, and voila! An ideal hardwood covering.
